Interrogative Pronouns in Swahili grammar are used to ask specific questions. They are very critical in forming basic sentences and can be utilized to obtain details about objects, places, people, and time. In Swahili grammar, some common interrogative pronouns include ‘nani’ (who), ‘nini’ (what), ‘lini’ (when), ‘wapi’ (where), ‘kwa nini’ (why), and ‘gani’ (which). The Sentence structure may often vary according to the used interrogative pronoun.
